Turn Vibe Code
Into Secure Code.
Scan once, watch forever. Guardian monitors your app 24/7 and alerts you the moment a deploy, plugin update, or new feature opens a security hole.
How Guardian Works
Three steps from "I hope this is secure" to "I know it is."
1. Connect Your App
Link your GitHub repo or drop in your live URL. Guardian connects securely — no agents, no CLI, nothing to install.
2. Deep Security Scan
Guardian simulates 500+ real-world attacks, targeting the exact gaps that AI code generators leave wide open.
3. Stay Protected, Always
Fix the issue, then let Guardian keep watching. Every new deploy, plugin update, or code change is automatically re-scanned. You get alerted the moment something breaks.
We check what AI tools miss.
The parts of your app that ship broken because no one thought to look.
Database Rules
Finds missing Row-Level Security in Supabase and Firebase before your users' data leaks.
Payment Webhooks
Validates Stripe & LemonSqueezy endpoints for signature verification holes.
Secret Git Leaks
Scans your full commit history for .env files and API keys accidentally pushed to GitHub.
Live Alerts
Get notified instantly when a deploy or update introduces a new vulnerability — before your users find it.
Find holes before hackers do.
Guardian scans your live app the way an attacker would — probing endpoints, checking rules, and surfacing the gaps that slip through every code review.
Supabase RLS disabled on `orders` after migration v2.4
Stripe webhook missing signature check — /api/webhooks/stripe
Auth session leak patched — marked safe
Know the second something breaks.
Every deploy, plugin update, or new feature triggers an automatic re-scan. If something opens a hole, you get an alert before your users ever notice.
Founders ship safer, faster.
From indie hackers to early-stage teams — here's what they found before it became a problem.
"I literally just copy-pasted whatever Cursor told me. Guardian found that I forgot to set up RLS on my database. Caught it before my Product Hunt launch!"
"Finally, a security tool that doesn't require a PhD. It plugged right into our Vercel workflow and caught our Stripe keys before they hit GitHub."
"It tells me exactly where the AI messed up, explains the fix in plain English, and lets me ship new features without the anxiety."
